Question:
a. State what is meant by:
i. A perfectly elastic collision
ii. A completely inelastic collision.
b. A stationary uranium nucleus disintegrates, emitting an alpha-particle of mass 6.65 × 10−27 kg and another nucleus X of mass 3.89 × 10−25 kg.
i. Explain why the alpha-particle and nucleus X must be emitted in exactly opposite directions.
ii. Using the symbols vα and vx for velocities, write an equation for the conservation of momentum in this disintegration.
iii. Using your answer to part b ii, calculate the ratio vα : vx after the disintegration.

I am a first class graduate of Physics and I am currently a Master's student in the Department of Physics, Federal University of Technology Akure, (FUTA) Nigeria. I am specialized in helping high school and college students with their maths, chemistry and physics assignments and also tutoring them on those two subjects. I have over 3 years of experience tutoring online and almost 5 years experience teaching offline making a total of 8 years teaching experience, in 2010 when I graduated from high school, I was the 3rd best chemistry student in the Awokoya chemistry competition organized by the chemical society of Nigeria (CSN). I have worked with online organizations where I helped both high school and college students with their physics and calculus assignments, respectively. Before teaching a session, I ensure that I consult different textbooks when preparing my lessons and also ensure that I give my students numerous examples in other to broaden and solidify their understanding of the concepts being taught. I also ensure that I give explanation in a manner that makes my students understand quickly and catch up easily, giving real life examples and applications especially when am teaching physics. This makes me a highly sort after teacher among students in my community here in Akure. Feel free to contact me anytime if you need help with your Maths, Physics or Chemistry assignments or if you are in need of a friendly tutor/guardian in those subjects.
